Swine flu, also known as H1N1, is an influenza virus that emerged in 2009 and caused a global pandemic. The document provides information on the symptoms, transmission, and prevention of swine flu infection. Key symptoms include fever, cough, sore throat, and body aches.

8. Human Infection…How it can happen? What are the signs and symptoms of swine flu in people? The symptoms of swine flu in people are similar to the symptoms of regular human flu and include fever, cough, sore throat, body aches, headache, chills and fatigue. Some people have reported diarrhea and vomiting associated with swine flu. Like seasonal flu, swine flu may cause a worsening of underlying chronic medical conditions. How does Swine flu spread? People usually get swine influenza from infected pigs, however, some human cases lack contact history with pigs or environments where pigs have been located. Spread of this swine influenza A (H1N1) virus is thought to be happening in the same way that seasonal flu spreads. Flu viruses are spread mainly from person to person through coughing or sneezing of people with influenza. Sometimes people may become infected by touching something with flu viruses on it and then touching their mouth or nose.
